SOLAR SYSTEM

Detailed explanation-1: -The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Detailed explanation-2: -Richter Scale is used to measure the magnitude of an earthquake. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9.

Detailed explanation-3: -A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.

Detailed explanation-4: -The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930’s for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.
